After having to wait through a heavy, but not unusually heavy, thunderstorm, I was riding home from work when, topping a rise suddenly found myself facing a flooded dip in the road - going too fast to stop. It has never flooded like this before. I was left with no choice but to power through the 2 to 2.5 feet of muddy water hoping to get out the other side before something got ruined.
No such luck. The motor now will not start turning until given an initial spin, thereafter it runs roughly and noisily, at slow speed, getting smoother (nearly normally) at top RPMs. I rode it slowly home (about 5 miles) in this condition - maybe not a good idea.
I dried the wiring connectors and checked for evidence of water intrusion into the controller. It does not look like water got in the controller.
The only fully submerged item was the motor, so my best guess is bad hall sensors - maybe just temporarily until they dry out?
Matt, I recall that you once disassembled an e-max motor? Any tips?
Thanks for any advice.
